elements of its suture-line are important distinctions from the earlier 
stock. 
P. humei, nov. (Plate V, fig. 4), has more numerous but less prominent 
inner tubercles, and more distinct and fewer outer nodes.

pp. 240 and 242. 
1921. Schloenbachia umbulazi, var. spinifera, v. Hoepen, loc. cit., p. 37,

1921. Pseudoschloenbachia papillata (Crick MS.), Spath, Pondoland, 
p. 43, pi. vi, figs. 2a, b. 
This form is sufficiently distinct from P. umbulazi to be accorded specific 
rank.

(Plate VII, fig. 1 ; Plate VI, fig. 4.)

1921. Schloenbachia umbulazi, var. griesbachi, v. Hoepen, loc. cit., p. 35 ;

Crick's long description of this species is omitted. The dimensions of 
the holotype are : 103 — 51 — 25 — 14 ; those of the paratype : 33 — 52 
— 26 — 13. The suture-line of the holotype was figured by the writer 
on a previous occasion. 
Incertae sedis.

It is interesting to note that Dr. van Hoepen remarked the resemblance 
of young examples of Pseudoschloenbachia papillata (his Schloenbachia um- 
bulazi, var. spinifera) to Grossouvre's Muniericeras lapparenti. The tuber- 
culate periphery of the present form, however, separates it from the genus 
Pseudoschloenbachia, and it may be only a heterochronous homceomorph of 
the Lower Senonian Muniericeras.
